wut? idempotent is any operator T such that T^2=e the identity. for example ring elements can be idempotent https://en.m.wikipedia.org/wiki/Idempotent_(ring_theory) https://en.m.wikipedia.org/wiki/Idempotent_(ring_theory). it's not just characteristic of linear operators.
- CarlsJrMints 7y agoIdempotence means T^2=T. Are you thinking of involution? https://en.wikipedia.org/wiki/Involution_(mathematics) https://en.wikipedia.org/wiki/Involution_(mathematics)
